AXLE-FASTENING.

SPECIFICATION forming part of Letters Patent No. 672,560. dated April 23, 1901.

Application filed January 21, 1901. Serial No, 44,006. (No model.)

To all whom it may concern:

Be it known that I, CLEMENS KUOHENBROD, locksmith, residing at Lindliugerstrasse, Hattersheim, Germany, have invented new and useful Improvements in Safety Devices for Axle-Fastenings, (for which I have applied for Letters Patent in Germany, application K. 19,095/63", dated January 26, 1900, and application for useful model, K, 11,714/63,

dated January 26, 1900,) of which the following is a specification.

The present invention relates to a safety device for axle-fastenings, the purpose of which is not only to prevent the said fastenings from opening independently, but also to provide means for counteracting even the slightest wear of the friction-surfaces of the axle-box and fastening-nut by tightening the latter, so that even the slightest lateral play of the axle is prevented -that is to say, the fastening can be adjusted to any desired point, and thereby prevented from opening independently.

In the annexed drawings, Figure 1 represents an elevation of the device, and Fig. 2 a

longitudinal section thereof.

a. is the journal of the axle, at the end of which is a screw-threaded gudgeon a. In the end of the said gudgeon a. is a recess a in the direction of the longitudinal axis of the former. This recess a receives the prismatic or squared continuation d of the tiebolt d, the screw-threaded part of which passes through the central opening b of the fastening-nut b. Between the threaded and the squared parts of the tie-bolt d the latter is provided with a flange (1 The tie-bolt d is directly connected both with the axle and the fastening-nut, with the former by its 0 squared part (1, which engages the recess in the gudgeon a, and with the latter by the nut c, which is screwed upon the screwthreaded part of said tie-bolt.

The action of the safety device is as fol- 5 lows: W ion the axle-box e has been placed upon the journal aof the axle, the fasteningnut b, into which the tie-bolt cl has been first introduced, is first screwed on so far that the part cl engages the gudgeon a. This can easily be effected, if necessary, by turning the exterior end of the bolt (1. Then the fastoning-nut is screwed farther onto the gudgeon until it has reached the desired position with the axle-box e on the inclined portion 1) of the nut 19, the tie-bolt d bearing through its flange d against the base of the fasteningnut and its end 61 entering further into the recess in a. Thereupon the nut c is screwed onto the projecting end of the tie-bolt (1 until the flange d is pressed tightly against the base of the fastening-nut b and the nutc presses firmly against the top of the fasteningnut, so that complete security is obtained, because none of this pressure bears upon the thread of said fastening-nut b and the exten- 65 sion d prevents any rotation.

When the fastening is to be tightened, it is only necessary to loosen the nut c, tighten the nut b, and then secure the fastening again by means of the nut o.

Now what I claim, and desire to secure by Letters Patent, is the following:

1. In a safety device for axle-fastenings the combination with an axially-recessed gudgeon and a fastening-nut of a screw-threaded tie-bolt passing through an aperture of the said nut and having a continuation for entering the recess in the gudgeon and a nut fitting on the said screw-threaded tie-bolt and adapted to connect it tightly with the said fastening-nut substantially as described.

2. In a safety device for axle-fastenings the combination with an axially-recessed gudgeon and a fastening-nut of ascrew-threaded tie-bolt having a flange and passing through an aperture of the said nut and having a continuation for entering the recess in the gudgeon and a nut fitting on the said screwthreaded tie-bolt and adapted to connect. it tightly with the said fastening-nut substano tially as described.

3. In a safety device for aXle-fastenings the combination with an axially-recessed gudgeon,a fastening-nut and an axle-box of a screw-threaded tie-bolt passing through an In testimony whereof I have signed my aperture of the said nut and having a conname to this specification in the presence of tinnation for entering the recess in the gudtwo subscribing Witnesses.
